A Guide To Silicone Sealants & Their Types

A Guide To Silicone Sealants & Their Types

Adhesives are well-known components for the functioning of any industry. There are different types of adhesives, one being silicone sealants, also known as water-resistant adhesives. It is commonly applied with the help of a tube but is also available in the market in large cartridge formats. 


In this blog, we’ll learn about the meaning and types of silicone sealant.


What is silicone sealant?

It is a gel-like substance, different from other adhesives in its chemical composition. They are used to create an airtight or watertight seal between the surfaces. Silicone sealant is much better in durability and stability while withstanding extreme temperatures. 


The curing process is one of the most important aspects when applying silicone sealants. The ideal temperature for this process is between 40 to 100 degrees Fahrenheit. The humidity level should be between 5 to 95%. In some situations, the curing process may take more than 24 hours to complete. It entirely depends on the thickness of the application of silicone sealant. 


Types of sealants

There are different types of sealants used in the market, and their use varies from industry to industry. 


General-purpose silicone sealant

This silicone-based sealant is mainly used for plumbing, sanitary applications, ductwork sealing, metal-to-metal joints, and standard glazing. General-purpose silicone sealant is highly resistant to UV radiation, ozone, and extreme temperatures. It is easy to apply and forms a flexible seal when exposed to moisture at room temperature.


Weather silicone sealant

It is a one-part engineering-grade sealant that cures at room temperature. Weather silicone sealant is used in bonding numerous kinds of materials like glass, aluminum, and concrete together. 


Neutral silicon sealant

This silicone-based sealant is commonly applied in applications involving granite and marble. It is suitable for both indoor and outdoor applications. For, instance, you can choose Neutral Silicone Sealant which is applicable for non-structural glazing; panel stiffener applications, and demanding sanitary applications including joining bathtubs as well as washbasins or other such purposes. It is also used to seal windows, door frames, and sealing uses of everything from marble/stone to plastic via concrete brick, etc.


Hybrid silicone sealant

The hybrid silicone sealant is used for both internal and external sealing purposes in various construction and building applications. It can be used in the bonding of glass, metal, panels, and profiles. 


Acryfill Silicone Sealant

Acryfill silicone sealant is developed from specialized chemicals that help in applying a thin and smooth fill over the surfaces for bonding. It is used for sealing low-movement joints like window and door frames, sealing duct holes, and many other places where low-movement is expected. 


Uses of silicone sealants

One of the most common uses of silicone sealants is creating a waterproof and airtight seal between the surfaces to keep out unwanted air and moisture. On a general basis, the uses of silicone sealants fall into four categories: manufacturing, home repairs and maintenance, glass and plastic bonding, and construction sealing. They are preferred above adhesives and other sealants due to their high flexibility. It creates a tough, yet rather elastic seal over the surfaces to hold the bond extremely well over the years. 


Apart from the physical properties of silicone sealants, their chemical composition also makes them the best choice for industrial applications. They do not promote mold growth, are chemically unreactive, and bond effortlessly with other materials. The curing process of silicone sealants is pretty much simple. Users just have to wait for some time and allow the liquid gel to set. 



In this blog, you learned about the meaning of silicone sealant and its various types. Silicone sealants are the top choice for any industry when it comes to the types of adhesives they should deploy in the field. Its unique chemical and physical properties offer flexibility, durability, and strength for bonding the surfaces. At resil, we manufacture silicone sealants suitable for every type of task and the industry. 


If you are looking for the best type of adhesive for your task, look no further. Silicone-based sealant can fulfill your requirements in every sense. Its resistance to UV radiation, ozone, moisture, and extreme weather temperatures makes it your best choice among other sealants in the market.
